SMALL IS POWERFUL 63alternately project clear images onto the retina, and blurred, out-of-focus (defocused) images in front of the retina. The wearer can see clearly while the defocused image simultaneously sends a signal to the eye to slow down its growth as it tries to shorten the eyeball to focus the defocused image on the retina. In clinical trials, DISC was proven to slow myopia progression by 60% among Hong Kong schoolchildren between the ages of 8 and 13.Overcoming technical challengesHowever, eye health issues prevent some schoolchildren from wearing contact lenses. Some are simply too young to maintain personal hygiene or follow contact lens care and cleaning routines. In response to this challenge, VST has developed a spectacle lens version of the DISC lens. Nevertheless, developing such a lens Ir Prof. Benny Chi-fai CHEUNGChair Professor of Ultra-precision Machining and Metrology, Department of Industrial and Systems EngineeringDirector, State Key Laboratory of Ultra-precision Machining Technology (The Hong Kong Polytechnic University)Director, The Hong Kong Polytechnic University-Wenzhou Technology and Innovation Research InstituteProf. Cheung is a leading scholar in his pioneering and sustainable research in ultra-precision machining technology and precision metrology.
